It provides a local messaging test tool that mimics cloud-based messaging infrastructure to verify message producer and consumer behavior. The project can be deployed as a standalone service or as an embedded emulator that runs directly within a Java application process to remove external dependencies. It includes a web-based queue management interface for monitoring queue statistics and managing messages visually. The system supports in-memory message storage with optional file-based state persistence to maintain data consistency across restarts. It also provides server health checks and exposes internal metrics via management beans for external monitoring. ## Tags ### Development Tools & Productivity - [Cloud Service Emulators](https://awesome-repositories.com/f/development-tools-productivity/development-environment-management/cloud-service-emulation-interception/cloud-infrastructure-emulation/cloud-service-emulators.md) — Acts as a local cloud service emulator by mimicking Amazon SQS behavior and APIs. - [Local SQS Development](https://awesome-repositories.com/f/development-tools-productivity/local-sqs-development.md) — Enables developing and testing SQS-dependent applications without needing cloud connectivity or accounts. ### Artificial Intelligence & ML - [Messaging Broker Emulators](https://awesome-repositories.com/f/artificial-intelligence-ml/external-server-connectivity/in-memory-testing/messaging-broker-emulators.md) — Implements an in-memory messaging broker emulator for testing logic without external infrastructure. ### Data & Databases - [In-Memory Queues](https://awesome-repositories.com/f/data-databases/in-memory-data-stores/in-memory-queues.md) — Utilizes in-memory queues for high-performance local emulation of messaging services. ### DevOps & Infrastructure - [Embedded Queue Servers](https://awesome-repositories.com/f/devops-infrastructure/application-server-deployments/embedded-queue-servers.md) — Supports running the queue server directly within the application to eliminate external dependencies.
